Had connection practically everywhere…
Had connection practically everywhere we went throughout Japan. Took a little while to understand how to set it up. (Do I click on “Activate eSIM” before or after I arrive in the new country? How do I make sure my own wireless company doesn’t activate when I arrive at the new country?) But after figuring that out, when we arrived at our destination, our phones seamlessly switched to Ubigi. Definitely will use it again!!

So simple. So easy.
I am not very tech savvy and this was easy. The setup was simple and it automatically kicked in as soon as I reached Japan. The price was also excellent. I'll use it again.

Generally worked well
Generally worked well enough. connection dropped a couple of times over 3 weeks, and needed resetting by switching to flight mode and back again.
